As I sadi elsewhere I dropped highmem support for now as the 33-rt
hackery to make it work is just ugly as hell and anything above 4G is
even in mainline a complete disaster.

If possible, just run a 64bit kernel on your machine (you can still
use 32bit userspace) or you have to wait until someone comes up with a
reasonable fix for that problem, unless you are the one tackling it :)

Thanks,
